UNITED STATES GEORGE A. BONELLI, OF KINGMAN, ARIZONA.

SPIRAL-WIRE-FORMING DEVICE.

Application filed October 31, 1921. Serial No. 511,613.

To all whom it may concern:

Be it known that I, GEORGE A. BoNnLLI, a citizen of the United States, residin at Kingman, in the county of Mohave and state of Arizona, have invented new and useful Improvements in Spiral-lVire-Forming Devices, of which the following is a specification.

My invention relates to a wire coiling device, the principal objects of my invention being to provide a relatively simple and practical device that may be advantageously and economically employed for the rapid coiling of wire that is utilized for springs or for coiled reinforcing members for concrete construction, and particularly for concreteor cementitious pipe.

Further objects of my invention are to provide a wire coiling machine that is of relatively simple structure capable of being easily and cheaply produced and which may be adjusted to form coils of different diameters and with the coils or convolutions disposed immediately adjacent to each other or spaced apart, which latter arrangement is desirable in the production of certain forms of springs and reinforcing elements.

With the foregoing and other objects in view, my invention consists in the features of construction and combination and arrangement of parts hereinafter more fully described and claimed, reference beinghad to the accompanying drawings, in which:

Figure 1 is an elevational view of a wire coiling device of my improved construction;

Fig. 2 is a side elevational .view of the wire coiling machine;

Fig. 3 is a detail perspective view showing the forms for the production of cementitious pipe, with a reinforcing member arranged between said forms, which reinforcing member comprises an open. coil of wire that is formed upon my improved machine;

Fig. 4 is a sectional view similar to Fig. 3 and showing the reinforcing memberin the form of a closed coil of wire that is formed by my improved machine.

Referring by numerals to the accompanying drawings, which illustrate a practical embodiment of my invention, 10 designates the body of the machine which body comprises a substantially rectangular blo k of metal and which isprovided on its lower end with a pair of laterally projecting ears or lugs 11 that are adapted to receive the edge of a suitable support, for instance, a table, and to firmly secure the machine in position upon said support a clamping screw 12 is seated in the lower one of lugs 11 and is adapted to engage and clamp the edge pf the table against the upper one of said ugs. I

The upper left hand corner of the block 10 is provided with a recess 13, thereby forming at said corner a pair. of spaced ears or lugs 14, and journaled therein is a short shaft 15 carrying on its forward end a roller 16 having a groove formed in its periphery, and on the opposite or rear end of said shaft is fixed a pinion l7.

Journaled in the ears 14 immediately adjacent to shaft 15 and preferably in the same horizontal plane therewith is a shaft 18 on the forward end of which is secured a grooved rol er 19 that lies immediately adjacent to roller 16. Secured on the rear end of shaft 18 is a pinion 20 that meshes with the pinion 17 on the rear end .of shaft15.

J ournaled on shaft 15 between the ears 14 is the lower portion of an upwardly projecting block 21, and journaled in the intermediate portion thereof is a horizontally disposed shaft 22 carrying on its forward end a grooved roller 23 that normally occupies a position adjacent to and above roller 16. Secured on the rear end of shaft 22 is a pinion 2 1 that meshes with pinion 17 on the rear end of shaft 15.

Pivotally connected to a pin 25 that projects rearwardly from the upper portion of block 21 is the upper end of an arcuate rod 26, thesame projecting laterally and downwardly and the end portion of said rod passes through an aperture that is formed in the rear end of a bolt 27 which latter passes through the upper right hand corner of block 10. The forward end of bolt 27 or that portion which projects forwardly of block 10 is threaded to receive a lock nut 28 and mounted upon said bolt 27 beneath said nut is the outer end of a plate29. the

inner end thereof being bent into an inclined plane as designated by 30, thereby providing a spreading member which when moved upwardly so as to engage the coils of wire formed by the grooved rollers 16, 19 and 23 will spread or separate the convolutions thereof to form open coils. This arrangement is desirableinthe production of certain forms of springs and reinforcing elements.

J ournaled in the lower left hand portion of block 10 is a horizontally disposed shaft 31 on the rear end of which is fixed a gear wheel 32, and the teeth thereof. mesh directly with the teeth of pinion 17. Secured to the rear face of this gear wheel 32 is the inner end of acrank handle 33.

In the operation of my improved wire coiling machine, the device is clamped to the edge of a support and the end of the section of wire to be coiled is inserted between the grooved rollers 16 and 23, as shown by dotted lines in Fig. 2, and the end of said wire is extended downwardly between the grooved rollers 16 and 19.

Crank handle .33 is .now engaged and actuated to rotate shaft 31, and the rotary motion thereof will be transmitted through gearwhee'l'32 to pinion .17 and from the latter to pinionsQO and .24, and, consequently rotary motion will be imparted to the grooved wheels 19 and 23 that are associated with grooved wheel 16.

Thewire inpassing between the grooved wheels 16, 19 and 93 will be formed into a coilas shown in Fig. 1, whichcoil it is produced gradually moves outwardly or away from the forming wheels. Under nor mal conditions, or with the spreadi her 30 shifted into position so that ofengagement with the coil of wire, it is being formed, the convolutions of said coil will lie immediately adjacent to each other, thereby producing a closed orclose coil. In the event that it is desired to produce an open coil or a coil wherein the convolutions are spaced apart, the inclined end 30 of member 29, is raised until it engages be tween the coils of wire as they pass from be tween the grooved rollers 16 and 19 and as aresult said coils will be spread apart. Obviously, the vertical adjustment of the spreader-30 will regulate the space between the convolutions of .the coiled portion of the wire. i

To regulate the diameter of the convolutions formed by the grooved rollers while the machine is in operation, block 21 carryingigroovedroller 23zis swung upon shaft 15 so as to adjust grooved roller '23 toward or away from roller '19, which adjustment is attained by moving the lfree-end of arcuate rod 26 through the opening in the end of bolt 27,..and :after the parts-have been properly adjusted nut 28is tightened to. lock the aren ate .rndinits adjusted position. As grooved roller 23is adjusted toward-the roller 19, the convolutiens of the coiled wire will be :rel-

body having spucadca s, a. l-

may rest upon or be secured to the floor,

and, further, shaft 31 may be equipped with a belt receiving pulley or sprocket wheel and driven from any suitable source of power.

Thus it will beseen that I have provided a relatively simple and practical machine forcoiling wire that is to be used for a variety of purposes, for instance, in the production of bed and furniture springs and for coiled wire spacing members and "reinforcements for 'cementitious work, and par ticularly tubular members of concrete or cementitious material.

By utilizing wire that has a certain degree of resiliency, coil springs of various lengths and. diameters may be readily produced, and said springs may be utilized for compression or retractile purposes.

In Figs. 3 and 4, I have shown pairs of concentrically arranged cylinders or :forms that are utilized in the construction of cementitious pipe, and with coils of wire arranged in the spaces betweensaid forms to serve as spacers and reinforcing members.

Various changes in the size, form and construction ofthe parts of my improved wire coiling-machine may be made and substituted for those :herein shown and described without departing from the spirit of tiny invention, the scope of which is set forth in the appended claims.

I claim as my invention:

1. A wire coiling device comprising a body, a member, a shaft extending through the member and body to rotatably support the former on ithe latter, a roller fixed to the shaft, a second shaft journaled in the mem her, a roller fixed-to the second shaft, a third shaft journaled in the body, a. roller carried by the third shaft, means for actuating all of said shafts, and 'acurved arm adjustably connected to the body for holding the member in any desired position.
